Course Description

The course will lay out the founding ideas of some of the more advanced C# topics for you in a way that makes them easier to understand.
The course is aimed at students that have some coding experience in general and with C# in particular, as well as some Object Oriented Programming experience. Not all topics require OOP knowledge, but it will be easier for you to understand those that do.
The topics that we are covering are:
  • LINQ - LINQ is kind of a language within the C# language, it has its own syntax, but its very easy and very enjoyable to use. LINQ is used to work on collections like arrays and lists, either to order them, or to extract information from them in many many many different ways. You will learn how apply LINQ filters on base type collections like integers and strings aswell as on collections of custom types that you have created.
  • Lambda Expressions with LINQ methods - you will finally learn what a Lambda Expression is and how to apply it, in particular we will use it to perform LINQ operations with even less code, and later we will use it with Delegates and Events
  • Extension Methods - this is one of the coolest features of C#, they allow you to extend built in types and classes that you have no access to. For example the int[] has no built in method for sorting or reversing, we will learn how to do this!
  • Generic Methods and Classes - this is where things start to get tricky and a little bit complicated, but you should not be scared as I have prepared a couple of well explained examples that will answer all of the questionmarks in your head about Generics. Spoiler alert: we will create our very own List class! :)
  • Delegates - the simplest way in which a delegate can be described is, methods as variables, and that is just incredible. How? Well, you will understand soon enough!
  • Events - events are the next piece of the puzzle after Delegates, Events help us keep our code decoupled by creating non-coupled connections between classes
  • Asynchronous Programming - asynchronous programming is a complex and frustrating topic, here we will learn how to make code that takes a lot of time to execute run on the background, while our main code continues executing
There are tons and tons of tutorials on Youtube and other websites, so why would you have to pay for this course?
The answer is very simple, in this course you will get every single lecture systemized in such way, that it ensures smooth transition between the previous and the following topic. Guaranteeing great learning experience.
There are no stones left unturned, everything is explained in great detail (but not too much, that would be boring :) )
The video lectures in the course are produced with the highest possible audio and video quality. No static noises to disturb you while you watch the videos, no blurry images, everything is crystal clear with crisp audio!Who this course is for:
  • Anyone who wants to improve their C# skills with New, Interesting and Challenging topics
  • Anyone who just finished Object Oriented Programming Training and is looking for the next step

Tod Vachev

I have graduated at Technical University of Varna as a Robotics Engineer. With several years of experience as a Passionate Developer and Engineer, I am now an Online Entrepreneur. Teaching is one of my passions, and what better and more impactful way to teach, than to do it online with thousands of students?
Currently focusing on providing quality education to tens of thousands of students across the globe, on subjects including:
- Programming, focusing on the C# Programming Language
- MATLAB, because this is a scientific tool that no scientist can do without
- Running Online Businesses that Earn Passive Income
For the past four years I have focused on the above and I have never stepped into the 9 to 5 world, I have worked in a company only once in my entire life and it lasted only 2 months. That's when I realized that, I can't learn the things that I want and I can't buy the things that I want buy working for someone else. You should start working for yourself aswell!
It does not matter if you want to become a developer or to run niche sites around the web, you can do both of these things in your own time as a freelancer or a business owner. And I can teach you how to do both of these things.
A little more about me:
I love tinkering with mechanics and

very simply yet very elegantly explained. Doesn't feel like an advanced course.

By William R. Smith on 3 months ago

As a former Java programmer with experience in C++ as well, I was anxious to see the differences between the languages. I learned quite a bit and would have felt I was learning more if this course had a more "project oriented" approach (like the Complete C# Course).

By Jatin Wadhwani on 3 months ago

Wonderful!Covers all topics in so less time and so effectively!

By Daniel Terceros on 6 months ago

Bought this course because I enrolled to "object-oriented-programming-with-csharp-beginner-to-advanced" course previously which I really liked (see my review there).Excellent content and quality as expected. I wish we could have a "main project" to practice more like the course mentioned above, but overall this course is excellent

Course was ok. Limiting it to thread safe console applications avoids the issues of cross thread communication problems. a Real world example for Aynch/Await with a WinForm/WPF example would be nice. Other than that very good.

By Bussa Jayasimha Reddy on 3 weeks ago

Good examples,Easy to understand ...Thank you

By Charles Parcell on 5 months ago

Too much explanation of little things. I do care why you used a variable name. too much time explaining these sorts of things.

By Samira on 3 months ago

very good explanation on areas that most juniors/intermediates have problems with.

By ??? Lee on a month ago

great but this course is for beginners

By Faith Welch on a month ago

It is very detailed with great examples. He explains each topic thoroughly and it is easy to follow along.

By Jamie LaFountain on a month ago

Clear, concise examples, and well paced.

Another great course from Tod. I highly recommend his C# courses over many of the others here on Udemy. If you're looking for clear explanations of what's actually being done and can be done, Tod's courses are definitely the ones you should be taking.One con to this course is the lack of exercises and practicing what is being explained, although by this point perhaps it's expected that you'll just go off and practice on your own.
